1. Driver Information Center (DIC) Switch Malfunction

Circuit/System Description

The driver information center (DIC) switch is a multiplexed switch. Battery power is provided to the DIC switch via the instrument panel cluster (IPC). The DIC switch signal circuit is pulled up to battery voltage in the IPC. The IPC also provides the DIC switch with a low reference circuit. The switch input to the IPC is pulled low or grounded when a switch is activated. The DIC switch is a momentary contact switch that connects a series of resistors in a resistor ladder format. The IPC monitors the DIC switch signal circuit to determine the DIC switch inputs. Each switch state corresponds to a certain resistance value. The IPC determines the switch pressed by the voltage drop across the resistors. A stuck switch or a short to battery sets a DTC.

The Trip/Fuel switch is monitored on a separate circuit provided by the IPC. The TRIP/FUEL driver information center select menu switch signal circuit is monitored for a stuck switch but not a short to battery.

Conditions for Running the DTC

The ignition is in ACCESSORY or RUN.

Conditions for Setting the DTC

B3567 59

The IPC detects that the DIC switch is stuck.

B3567 01

The IPC detects that the DIC switch signal circuit is shorted to battery.

Action Taken When the DTC Sets

The IPC ignores the DIC switch inputs.

Circuit/System Verification

Ignition ON, verify that when the DIC switches are pressed and released the DIC scan tool parameters toggle between Active and Inactive.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the DIC switch assembly.
2. Ignition OFF, test for less than 1 ohm between the low reference circuit terminal 2 and ground.

⇒	If greater than the specified range, test the low reference circuit for an open/high resistance.

3. Ignition OFF, test for less than 5 ohms between the ground terminal 6 and ground.

⇒	If greater than the specified range, test the ground circuit for an open/high resistance.

4. Ignition ON, verify that all of the scan tool DIC Switch parameters are Inactive.

⇒	If any are not Inactive, test the signal circuit terminal listed below for a short to ground. If the circuit tests normal, replace the IPC.

•	Signal Terminal 1

•	Signal Terminal 3

5. Ignition ON, install a 3-A fused jumper wire between the signal circuit terminal 1 and the low reference circuit terminal 2. Verify the scan tool DIC Switch parameters, except the DIC Fuel Info. parameter, are Active.

⇒	If any are not Active, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the IPC.

6. Ignition ON, install a 3-A fused jumper wire between the signal circuit terminal 3 and ground. Verify the scan tool DIC Fuel Info. parameter is Active.

⇒	If not Active, test the signal circuit for a short to voltage or and open/high resistance. If the circuit tests normal, replace the IPC.

7. If all the circuits test normal, test or replace the DIC switch assembly.
